LG 49UB8500 Owner's Manual page 5

• Dot Defect
The panel is a high technology product with
resolution of two million to six million pixels.
In a very few cases, you could see fine dots
on the screen while you're viewing the TV.
Those dots are deactivated pixels and do not
affect the performance and reliability of the
TV.
Generated Sound
•
Cracking noise A cracking noise that occurs
when watching or turning off the TV is
generated by plastic thermal contraction
due to temperature and humidity. This noise
is common for products where thermal
deformation is required.
Electrical circuit humming/panel buzzing
A low level noise is generated from a
high-speed switching circuit, which supplies a
large amount of current to operate a product.
It varies depending upon the product.
This generated sound does not affect the
performance and reliability of the product.
• Take care not to touch the ventilation
openings. When watching the TV for a long
period, the ventilation openings may become
hot. This does not affect the performance of
the product or cause defects in the product.
• Do not install this product on a wall if it
could be exposed to oil or oil mist. This may
damage the product and cause it to fall.
• If the TV feels cold to the touch, there may
be a small flicker when it is turned on. This
is normal; there is nothing wrong with TV.
Some minute dot defects may be visible on
the screen, appearing as tiny red, green, or
blue spots. However, they have no adverse
effect on the TV's performance. Avoid
touching the LCD screen or holding your
finger(s) against it for long periods of time.
Doing so may produce some temporary
distortion effects on the screen.
IMPORTANT SAFETY INSTRUCTIONS
Preventing image burn or burn-in on your
TV screen
• If a fixed image displays on the TV screen for
a long period of time, it will be imprinted and
become a permanent disfigurement on the
screen. This is image burn or burn-in and not
covered by the warranty.
• If the aspect ratio of the TV is set to 4:3 for a
long period of time, image burn may occur on
the letterboxed area of the screen.
• Avoid displaying a fixed image on the TV
screen for a long period of time (2 or more
hours for LCD, 1 or more hours for the
Plasma TV) to prevent image burn.
